We might want to consider getting the Medical Industrial Complex out of the way as a middleman (at least for anyone and everyone not in a clear and severely high risk mental condition). Trip sitter qualifications for 99% of the world: responsible-ish adult, sober, and awake.
The rest is pernicious money grabbing window dressing to enable the same industries that have saturated the world in ridiculous, designed to be habitual compounds (from lithium to benzos to SSRIs) that are either worthless, beneficial but addictive, or some combo of these).
Your.body. Your mind. Your consciousness. Your soul. Life is risk. Ingest whatever you like. Build whatever process to maximize the therapeutic potential, including professionals, but don't allow these powerful compounds to be doled out by the dastardly folks selling obesity drugs, statins, Vioxx, etc etc etc. Somehow, they'll fuck up a good thing and in the most idealistic scenario imaginable, they're drive the cost up 100x or more as the carve out there latest pound of flesh from a beleaguered, confused, depressed, traumatized global population.
Think about it..
